It's probably a good idea to practice come cell phone caution in light of studies linking cells and cancer. But Real Age says cell phones are not all bad -- they might even help you get skinny.

Use your cell to chat with a weight loss buddy and you might stick with your diet better. Just keep your conversation supportive and you'll benefit. Of course, talking in person is best -- no cancer risk here -- and if you have a land line, go this route. If these are not options for you, well, then, the cell will do.

In one study, overweight folks who had lost 18 pounds each through a weight loss program were followed to see how long they could keep their pounds off. Those who spent time each month talking on the phone with an inspirational friend scored best. It's not the phone itself that does the trick. It's the positive human reinforcement that helps you resist daily temptations. It's just that we're all so connected by cells these days -- it's how most of us communicate. So dial away. And be careful at the same time.
